Replace iMac hard disk - Backup iTunes (Devices sync)

[aka.seim]

Hi.

I need to replace the hard disk of my iMac and I'm going to take this opportunity to make a clean install of Mountain Lion.

I have made a backup of iTunes folder that contains:
-Album Artwork forlder
-iTunes Library Extras-itdb
-iTunes Library Genius.itdb
-iTunes Library.itl
-iTunes Library.xml
-iTunes Media folder
-iTunes Music Library.xml
-Previous iTunes Libraries folder

I sync two iPhones and an iPad with this iTunes so I wonder if there is any other file or folder I have to backup and transfer in order that next iTunes recognizes my devices.

Thanks in advance.
